TUMBLING-BARREL.` i

Specification of Letters Patent.

Patented Aug. a7, 1907.

Application filed June 14,1905. Serial No. 265,225.

cago, Cook county, Illinois, have invented a certain' new and useful Improvement in Tumbling-Barrels, of which the following is a specification.

My invention relates to tumbling barrels in general, but moreparticularly to tumbling barrels of a size and character to be readily and easily adjusted by hand. Ordinarily, devices of this character comprise a rotatable receptacle called the tumbling barrel, and are adapted to receive the saw-dust and small castings to be treated-that is, to receive the materials or articles which are to be tumbled about for the purpose of taking off the sharp edges and smoothing down the rough surfaces. It is the practice to operate ythese barrels either by hand or by power, according to their size or capacity, and according to the character oi. the articles or materials to be treated. My invention, however, as stated, relates more particularly to tumbling barrelswhich are operated by belt and pulley or other powertransmitting connections, but which arev oi a size and character to be readily and easily adjusted or properly v tending to produce amore efficient tumbling action;

to provide an improved cover or closure for the end of the barrel,- which can be quickly opened or closed; to provide an improved arrangement whereby the axis about which the barrel rotates can be given any suitable or desired inclination; to provide an improved construction and arrangement which will permit the inclination of the *'barrel to be varied or changed without stopping its rotation; and to provide' certain details and features of improvement tending to increase the general efiiciency and serviceability of a tumbling barrel of this particular character.

To the foregoing and other useful ends, my invention consists in matters hereinafter set forth and claimed. In the accompanying drawings, Figure 1 is a side ele-i vation of a tumbling barrel involving the principles of my invention. Fig. 2 is a front elevation of the machine shown lin Fig. l. Fig. 3 is a top View of the removable cover or closure for the mouth or upper end of the tumbling barrel. Fig. 4 is an enlarged detail cros's-V section Vof the said cover or closure. Fig. A5 is an enlarged detail sectional view showing the method of connecting the side walls of the barrel to its base or bottom. Fig. 6 is an enlarged plan view of the yoke,

a portion thereof, as well as certain adjacent parts, be-

ing shown in section. Fig. 7 is an end view of the said yoke, showing the circular row of anti-friction rolls fortaking up friction between the yoke and the bottom of the tumbling barrel.

As thus illustrated, my invention comprises an upright standard or pedestal A having a base a adapted to y means of trunnions whereof one is simply a short pin or stud c and the other a rotatable shaft cl. The said shaft c1 is provided with fast and loose pull/eye c2 and c3, -whereby the shaft may be operated by ,a suitable belt. As illustrated, the said barrel Bis provided with a bottom b having secured thereto a shaft or axis b1, the latter being supported for rotation in bearings b2 and b3 carried at the opposite ends of the tilting yoke C. A power-transmitting connection, consisting of a bevel-- gear b4-on the said shaft or axis b",.and of a bevel-pinion b5 meshing'withthe said pinion and mounted on the shaft c1, is provided for communicating power and motion from lthe. fast pulley c2 to the said barrel. i The bevel-gear b1 has its hub portion adapted to engage the bearing b3, so as to act as a collar for the purpose of pre venting the shaft or axis b1 from being shifted endwise or displaced when the machine is operated. The upper end of the yoke is also provided with a thrust-bearing b6 provided with anti-friction rolls b7 adapted to bear upon the opposing thrust-bearing b8 formed on the bottom of the barrel. In this way, the said barrel is adapted to be rotated at any angle to which the said yoke C may be adjusted. Y

The inclination of the barrel, and of the yoke upon whichitis supported, may be changed or varied by any suitable means. vFor example, the said yoke may be 'provided with a semi-circular rack D adapted to engage a horizontally disposed screw or worm E, the

latter beingsupported in a bearing e carried by the up- V per portion of the pedestal or upright. The outer end ofthe shaft upon which the said screw or worm is mounted can be provided with a hand-crank e1, whereby the when the shaft is rotated. With this arrangement,

the split collar can be tightened sufficiently toact as a friction device for holding theshat in any position to .sition when it is desired to load it, and it may then be limeter of the barrel, and also with a movable catch which it may be rotated by .the said crank. 'In this way, the crank e can be employed for rotating the setscrew or Worm in either direction, so as to either rais or lower the barrel B.

For some kinds of work it may be necessary to give the barrel practically a horizontal position, while for other varieties of Work it may be found desirable'to give it a more or less inclined position. Furthermore, the barrel can be tilted up to a more or less vertical pogiven a more or less horizontal position when it is closed and put in operation. As shown, the-sides of the barrel are provided with spiral and internally arranged ribs b9 which increase the tumbling action-that is to say'f which enable the barrel to more efficiently treat the articles or materials placed within it. At its mouth or outer end, the said barrel is provided with a closure F adapted to fit tightly around the perimeter of the said barrel.

In order that the closure or cover may be quickly removed or replaced, it is provided with a couple of rigid or stationary catch devices f, each adapted to engage the rib or ridge b1 extending around the perdevice f1. This movable catch device consists of a bar having an end portion j2 adapted to extend over and engage the said bead or ridge b10 on the outside of .the barrel. At its inner end, the said bar is pivoted at f3 to the disk or crank-plate f4 which is secured to the rotatable stud or short shaft f 5. A handle f 6, secured to the upper or horizontal end of the said stud or short shaft, constitutes the means for rotating the disk or crank-plate f 4, and for thereby causing the catch device f 1 to move toward and away from the edge of the barrel, according to the direction of rotation. In this connection, it will be'seen that the inner end portion of the bar constituting the catch device fl is curved and brought around the stud or shaft f5 to its point of pivotal connection with the disk or crank-plate f4, thereby making possible the reciprocation of this bar by simply turning the handle f 6 one way or the other.

With this arrangement, the' said closure or cover Fcan be very quickly and easily removed or replaced, and, in addition, the cover is very firmly held in place upon the mouth or open end of the barrel. It will also be seen that the bottom of the barrel is preferably provided with radially and internally arranged ribs b, these ribs being also instrumental in increasing the efficiency of the tumbling action. In other words, the interior of the barrel is provided with radially extending bottom ridges or ribs, and with spirally arranged side ribs or ridges. I l

By referring to Figs. land 5, it will be seen that the cylindrical side walls of the barrel are secured to the base or bottom b by means of screws bm. Preferably, each screw extends through a slot or notch 1113 in the lower edge of the cylindrical side walls of the barrel,

whereby these screws can be loosened and the cylindrical portion of the barrel easily and quickly removed from the said base or bottom.

A set-screw c4 is inserted through the yoke and employedA for holding the stud or pin c against rotation in the yoke. The semi-circular rack D can be secured to the yoke by screws or bolts inserted in the threaded sockets d. Also, as illustrated, the shaft or axis b1 is provided with a shoulder 614 against which the bottom of the barrel is clamped and held by means of a nut b15 screwed upon the reduced and threaded outer end portion b16 of the said shaft. A key 617 can be employed for securing the bevel-gear b4 to the shaft b1; and a set- Screw c5 can be employed for securing the bevel-pinionv b5 to the shaft c1.

With a tumbling barrel of the foregoing construction, the materials to be treated can be readily and easily introduced into the interior of the barrel, and can be as readily and easily discharged therefrom. Furthermore, the position of the barrel can be easily changed or adjusted, according to the different requirements, and this can even be 'done while the barrel is rotating.

What I claim as my invention is:

1. A tumbling barrel comprising a tilting support, a shaft mounted in two separated bearings on 4said support and arranged at right angles to the axis of the latter, a power-transmitting connection including the bevel gear b4 between the said shaft and the axis of the tilting support, said `g'ear positioned between said bearings, a rotatable barrel secured to the end of said shaft, a thrust-bearingr for the bottom of the barrel, and means for giving the tilting support different positions. 5
